Method of joining the electrode lugs with a terminal of an electrochemical generator and generator

The electrode connection method has a ring or disc (12) used for holding the spaced tongues (2) of the electrode (1) in contact with the battery pole (3), during welding of the electrode tongues to the battery pole via a laser beam passing through the ring or disc, which has a thickness of between 0.5 and 1 mm. An Independent claim for a rechargeable electrochemical battery is also included.
